Studying Shock Wave Phenomena with a Shock Tube Application
Shock waves used to be a theoretical problem only. Then, shock tubes enabled experimentation, but it was costly and inefficient. Enter numerical modeling applications.

Keynote Video: Designing Improved Heart Pumps with Simulation
Abbott Laboratories designed “the most complex machine ever implanted into a human being” — an LVAD for heart failure patients — using multiphysics modeling. The result? Saved lives.

FEM vs. FVM
Finite element methods, finite volume methods, or a hybrid approach: Which is the best choice for CFD? It depends on the fluid flow problem you’re trying to solve.

Using Discontinuous Meshes for Conjugate Heat Transfer Modeling
You can use different discontinuous meshes in neighboring domains in COMSOL Multiphysics®. This capability comes in handy, particularly when modeling conjugate heat transfer problems.

Understanding Classical Gray Body Radiation Theory
Imagine how efficient an incandescent lamp with an infrared suppressing black body filament would be. Alas, classical gray body radiation theory tell us this “dream lamp” is an impossibility…

3 Approaches to Modeling Moving Loads and Constraints in COMSOL®
Learn 3 ways to model moving loads and constraints in COMSOL Multiphysics®: using variables, interpolation functions, and paths imported from CAD geometries.

Improving Architectural Designs with Building Physics Simulation
Building physics simulation can help engineers develop more energy-efficient architectural designs. We talked to Built Environments, Inc. to get a few examples of how.

Studying the Peltier and Seebeck Effects in Thermoelectric Devices
We go over 2 key concepts in themoelectricity, the Seebeck and Peltier effects, and how to account for them when simulating heating and cooling in thermoelectric devices.
